Description

Lip cosmetic composition comprising copolymerized silicone polymer, hydrocarbon-based oil and silicone powder

It relates to a cosmetic composition for lips comprising a silicone polymer, a hydrocarbon-based oil and a silicone powder.

Recently, the demand for liquid lip with velvet-like feeling is increasing in domestic and overseas markets. Since this formulation contains a large amount of silicone cross polymer gel, it can produce a soft, non-dry feeling and a matte finish, but it has the disadvantage of weak durability.

In order to improve the above disadvantages, a method of increasing the content of the silicone cross polymer gel to produce a non-smerging effect or adding a powder to increase the adhesion is used. However, the above methods have limitations such as generation of white bands due to a decrease in pigment dispersing power, grains protruding during product application, and wrinkle relief, so another method is required.

Under this technical background, research on a cosmetic composition for lips having a velvet-like feeling is being actively conducted (KR Patent No. 10-0239186), but it is still incomplete.

One aspect is to provide a cosmetic composition for lips comprising a silicone polymer, a hydrocarbon-based oil and a silicone powder.

One aspect provides a cosmetic composition for lips comprising a silicone polymer, a hydrocarbon-based oil and a silicone powder.

In one embodiment, the hydrocarbon-based oil may be at least one selected from the group consisting of isododecane, isohexadecane, dodecane, tetradecane and undecane.

The total weight of the silicone polymer and the hydrocarbon-based oil mixture may be 1 to 10% by weight, 1 to 8% by weight, 2 to 8% by weight, 3 to 7% by weight relative to the total weight of the cosmetic composition.

Manufacture of cosmetics for lips

Test Examples 1 to 4 of cosmetic compositions for lips were prepared with the composition shown in Table 1 below. After measuring wax and oil with a high boiling point in a beaker, the mixture is uniformly mixed at 2500 rpm for 5 minutes at a temperature of 80° C. or higher using an Agi-mixer. While maintaining the process temperature at 70~80℃, add the silicone cross polymer gel raw material and mix evenly using an azimuth mixer for 5 minutes. After adding the remaining raw materials, the mixture was uniformly mixed using an azimuth mixer for 15 minutes. After inputting the silicone crosspolymer gel raw material, the process proceeds while maintaining the process temperature of 60~65℃. Then, air bubbles were removed to prepare a cosmetic composition.

In Comparative Examples 1 and 2, silicone polymer/hydrocarbon-based oil mixture raw materials or silicone powder were not applied, respectively, and Test Examples 1 to 4 were mixed weight ratios of silicone polymer, hydrocarbon-based oil mixture, and silicone powder (10:1, 4: 1, 1:1, 1:4, 1:10) to confirm the effect.

Experimental Example 1: Confirmation of wrinkles in the cosmetic composition for lips

A test was performed to determine the degree of wrinkling of the cosmetic composition for lips.

The measurement method is as follows. After each application of the cosmetic composition for lips to the wrist of the subject, the motion of bending and unfolding the wrist is repeated 30 times to photograph the degree of the formulation accumulating between the wrinkles with a camera.

As shown in FIG. 1, compared to Test Examples 3, 4, 5 and Comparative Example 2, Test Examples 1 and 2 and Comparative Example 1 in which a silicone polymer/hydrocarbon-based oil mixture was applied at a higher weight than silica powder had fewer wrinkles. showed the phenomenon. Among them, the wrinkle incidence of Test Example 1 and Comparative Example 1 was similar.

Experimental Example 2: Confirmation of uniform application power of the cosmetic composition for lips

A test was performed to confirm the uniform application power of the cosmetic composition for lips.

As shown in FIG. 2, compared to Comparative Examples 1 and 2, Test Examples 1 and 2 using a mixture of a silicone polymer and a hydrocarbon-based oil and a silica powder of 10:1, 4:1 to Comparative Examples 1 and 2 using only a mixture of a silicone polymer and a hydrocarbon-based oil Comparative Example 1 showed better coating power. Among them, it was confirmed that Test Example 1 had the least amount of agglomeration and had excellent coating power.

Experimental Example 3: Confirmation of color durability of cosmetic composition for lips

A test was performed to confirm the color persistence of the cosmetic composition for lips.

The measurement method is as follows. After the cosmetic composition for lips is applied to the lips of the subject, the color remaining on the lips is measured immediately after application, after 4 hours, and after 8 hours. The measuring instruments are VISIA-CR (Canfield Scientific, Inc., U.S.A) and I-MAX PLUS (INGPLUS, Korea).

As shown in FIG. 3 , compared to Comparative Example 2, Test Examples 1 to 2 and Comparative Example 1 using a silicone polymer/hydrocarbon-based oil mixture at a higher weight than the silicone powder showed better durability. Among them, Test Example 1 had a color persistence of 93.1% for 8 hours, confirming that it was the most durable formulation.

Experimental Example 4: Confirmation of adhesion of cosmetic composition for lips

A test was conducted to confirm the spreadability and adhesion of the cosmetic composition for lips.

The measurement method is as follows. The cosmetic composition for lips was applied to the lips of the subject and about 20 test personnel were allowed to evaluate it. The evaluation scale is 1 point - very bad, 2 points - bad, 3 points - average, 4 points - good, 5 points - very good.

As shown in Table 2 below, when Test Examples 1 to 1 were applied to the lips, spreadability and adhesion were found to be superior to those of Comparative Example 2 corresponding to the existing velvet-type formulation. Although the spreadability was excellent in Comparative Example 1, only Test Example 1 had the best adhesion. That is, in the overall feeling of use, Test Example 1 was found to be the most excellent.
